MULTIPLE MACHINE-TABLE.

Speeication of Letters Patent.

Patented Get. 3,

Application led September 25,1915. Serial No. 52,575.

A To aZZfwwm t may concern.'

Be it known that I, Ci-iannns M.

Among the objects of the invention is to provide a means whereby a Job may be clampedv in the rough yto a table or platform and moved thereon from yone place Vto another, or from one machine to another, forthe operation thereon of varier@ processes, without necessitating the loosening ofthe job and rfc-.attaching it to another euijfport.

Another object of the invention is tb pro-4 vide a main support along` which a, series of independently movable tables may be roperated, under the control of asingle operator, for the purpose of bringing such tables severally into position for a particular portion of the worl A With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which-f Figure 1 is a side elevation of the invention; Fig. 2 is a plan view of the same; Fig. 3 is a transverse vertical section on the Iline 3 3 of Fig'. l; and Fig. 4 is a detail *portion of this support Yadjacent thelot11 is dovetailed as indicated at Within the interior of thesiipport 10 is a longitudinal power shaft l-having secured thereon a plurality 'of bevel pinions 14 meshing with corresponding-pimms 15 mount-ed upon short trans1e rse-sh"afts i6 journaled in one side Wall othe main support and in ARRANTS, a citizen of the United States, and a resi-l The power shaft 13 may be adjusted l'oug tudinally by means of bell crank or a similardevice 18 so as to bring all oi' the pairs of bevel pinions into or out of mesh simultaneously. In other words, wiiiie the power shaft may be operated continuously the shafts 16' may all be driven simultaneously upon shifting the pinions 14.- into mesh with the gears 15. On each ofthe short shafts 16 is mounted preferably i'rictionally a spur gear 19 meshing or adapted to inesh with' a rack 20 extending along the bottom of each work .table 21. For each main support 10 I provide a plurality of these individual work tables 21 all of which may be of the same character and interchangeable but in practice intended to have attached thereto a liob to be operated upon by the different machines for the same or different purposes depending upon .the character of the job,

for illustration, an automobile cylinder may be clamped to the table 21 and while thus clamped may be treated' at different positions along the main support for milling oii" on the end, rough bored, finished, reamed and drilled for bolts, these different operations being performed in turn by different operators along the line of the support. Each table Q1 has a tongue 22 operated in the dovetail 12, above mentioned.

Each table carries a movable catch such as indicated ,at-23 for engagement with the stop lug 24 on thestationary support, whereby such table will bestpopped automatically when it reaches the proper position adjacent the tool or machine, Vdifferent types of which are indicated in dotted lines in Fig. 2. The gears 19 being connected .frictionally to thel shafts 16 insure that no l.

damage will result to the power mechanism it the rotation `thereof is not 'stopped when the 'catchesengage the stops ors-in theevent that any of the tables should encounter an obstruction. The several .workin-en along the support 10 when their several', duties are" performed on as many jobs will release the catches 23 permitting all of the tables to progress one step, so that the next '#IYUQH may be performed on the vseveral ]obs. The several operators, however, will be relieved Astrom the trouble of clamping the jobs to their tables, the clamping being done initially and in a uniform manner upon the'scveral tables 21 before they yenter the main line of operation. When the table leaves the support l0 the work being performed upon the job, such job will be removed and the table will be free for attuchment of a new job in the rough and to be started at the head of the line again;

I claim- The combination of a. support adapted to be 'arranged adjacent a plurality of ma- Chines each of which is adapted to perform a different operation, Work tables mounted t0 travel on the support fronlvone end thereof tothe other, power means for operating the tables, and means for successively und the several machines, whereby provision is made for performing various operations on 15 the Work :carried by the tall-iles.

In testimony whereof I have signed my nume to this Spemficatmn 1n the presence of two subscrlhlng witnesses.
